Horseradish Root Crowns for Planting
Plant once. Harvest every year.
Horseradish (Armoracia rusticana) is one of the simplest perennial crops you can grow. Plant a crown, dig roots every fall, replant a few pieces, repeat. It doesn't need much — reasonable soil, reasonable moisture, room to spread.
Fresh-grated root produces sharp, volatile heat that fades fast with cooking and disappears entirely in a jar. Growing your own changes that. You grate it when you need it, and it's a different thing entirely.
We grow ours in southeast Kansas and sell bare root crowns with active growing points. These have already handled Midwest heat, cold, and variable rainfall — not greenhouse-raised starts.
Planting
Plant in spring as soon as soil is workable, or in fall before first hard frost. Set crowns 2–4 inches deep at a 45-degree angle with the top end up. Space 18–24 inches apart. Full sun preferred. Tolerates partial shade. Adapts to most soils but produces best roots in loose, deep ground.
Harvest
Dig roots in late fall after the first frost for best flavor, or in early spring before the plant leafs out. Replant a few pieces each time and the patch sustains itself indefinitely.
Management
Horseradish is persistent. Once established it will come back from any root piece left in the ground. Plant it where you want it long-term, or manage the bed edges each season. It's not invasive in the aggressive sense — but it doesn't give up a spot easily either.
Limited stock. Ships bare root in spring and fall.
Horseradish Root Crowns for Planting
How long until I can harvest? First harvest is typically fall of the planting year if you plant in spring. Roots won't be large yet, but they'll be usable. By year two the patch is fully productive.
How do I use fresh horseradish? Peel and grate the root immediately before using — the heat develops when the tissue is broken and fades quickly after. Mix with white vinegar to stabilize, or use fresh. Significantly sharper than anything jarred.
Does horseradish need to be contained? Best planted in a dedicated bed or edge space. It doesn't spread aggressively across a property, but it will regrow from root pieces left in the soil. If you want full control, harvest thoroughly each season and manage the edges.
Will it spread? It expands slowly from the crown and any root pieces left in the ground will regenerate. Give it a dedicated spot rather than mixing it into a bed you want to control tightly.
When do you ship? Spring, while planting conditions are appropriate. Order now — stock is very limited this season.
Can I grow it in a container? Possible but not ideal. Roots need depth to develop well. A large, deep container (15+ gallons) can work, but in-ground produces significantly better results.
Do you divide and replant after harvest? Yes — dig, harvest the large central root, and replant the smaller side roots and crown pieces. The patch sustains itself indefinitely this way.
